Abstract:
PURPOSE: A method generating a single thread program capable of executing an asynchronous multi task model and a recording medium including the program have no a limit condition for an execution period of task models and normally execute the multi task model even in that case of desynchronizing a basic execution period of the single thread program. CONSTITUTION: The standard clock(101) which is periodically updated based on a basic execution cycle of single thread programs(100) is established in the single thread program. An internal clock(111,121,131,141) is established in task models(110~140) executing a task in the single thread program. Whenever the standard clock is periodically updated, time of the internal clock and the standard clock is compared. When the standard clock is faster than the time of the internal clock, the task is executed through the task model.

Abstract:
PURPOSE: A device for controlling a homing filter of a radio frequency (RF) seeker and a method thereof are provided to increase an obscuring phenomenon of the RF seeker by controlling signals of the homing filter of the RF seeker. CONSTITUTION: A method for controlling a homing filter of an RF seeker comprises the following steps: determining whether or not the homing filter is initialized (S11); determining whether or not the predicted meeting time of a guided missile and a target is within a first predetermined time (S12); controlling a signal of the homing filter in a meeting mode (S14); controlling the signal of the homing filter in a normal mode when the predicted meeting time of the guided missile and the target is greater than the first predetermined time (S13); determining whether or not a prediction mode is maintained over a second predetermined time (S15); and performing an end mode when the homing filter maintains the prediction mode over the second predetermined time (S16).
